Question

Assume a student received the following grades for the semester: History, B; Statistics, A; Spanish, C; and English, C. History and English are 6 credit-hour courses, Statistics is a 8 credit-hour course, and Spanish is a 6 credit-hour course. If 4 grade points are assigned for an A, 3 for a B, and 2 for a C, what is the weighted mean grade for the semester

Answer 1

The weighted mean grade for the semester is 8.22

What is mean?

It is calculated by dividing the total number of values in a set of data, such as measurements or numbers, by the total number of values.

No. of credits for Spanish, History and English = 6

No. of credits for Statistics = 8

Grade points for A = 4

Grade points for B = 3

Grade points for C = 2

Weighted mean = (6 * 2 + 6 * 3 + 8 * 4 + 6 * 2) / 9

Weighted mean = (12  + 18 + 32 + 12) / 9

Weighted mean = 74 / 9 = 8.22

Hence, the weighted mean grade for the semester is 8.22.
